ABSTRACT

Introduction Food allergies have become a significant health concern worldwide, affecting individuals of all age groups. It is particularly challenging for parents who have children diagnosed with food allergies, as they bear the responsibility of managing their child's condition and ensuring their safety. This study aimed to assess the knowledge and awareness about food allergies among mothers with allergic children in the Aseer region, Saudi Arabia. Methodology A cross-sectional study design was employed, and data were collected through a structured questionnaire administered to 400 mothers. The participants were selected through convenience sampling. Descriptive statistics, including frequencies and percentages, were used to summarize the demographic characteristics, knowledge and awareness levels, prevalence of allergenic foods, manifestations of food allergies, and factors influencing food allergies. Chi-squared tests were conducted to assess associations between variables. Results The study revealed a balanced representation across different age groups among the surveyed mothers, with the highest proportion falling in the 31-40 years range. A significant proportion of mothers had a university education, indicating a relatively higher level of education among the participants. The majority of mothers were employed in governmental positions, followed by housewives and those working in the private sector. Regarding knowledge and awareness, a substantial percentage of mothers correctly identified key aspects of food allergies. However, knowledge gaps were observed, particularly in understanding the hereditary nature. The prevalence of allergenic foods varied, with seafood (fish, shrimp, and tuna) emerging as the most commonly reported allergenic foods, followed by eggs, milk, wheat, chocolate, fruits, nuts, and other food types. Manifestations associated with food allergies were reported, including skin, respiratory, eye, nasal, gastrointestinal, and other symptoms. The associations between different feeding methods and the occurrence of medically diagnosed food allergies were found to be non-significant. However, having other children with food allergies showed a highly significant association with the occurrence of food allergies in the current child. The age of introducing solid food did not demonstrate a significant association with the occurrence of food allergies. Conclusion This study provides insights into the knowledge and awareness about food allergies among mothers with allergic children in the Aseer region, Saudi Arabia. While mothers demonstrated a reasonable understanding of food allergies, knowledge gaps were identified, particularly regarding the hereditary nature. The prevalence of allergenic foods aligns with previous studies, although variations across populations should be considered. The manifestations reported by the participants corroborate known allergic reactions, necessitating further analysis.

ABSTRACT

BACKGROUND: definite figures of allergy to wheat and strawberries in Egypt are lacking. We investigated IgE-mediated sensitization to wheat and strawberry among a group of allergic children, and the relation between wheat and strawberry sensitization. PATIENTS AND METHODS: This study comprised 256 children, with physician-diagnosed allergy: bronchial asthma (98 patients), allergic rhinitis (28 patients), atopic dermatitis (53 patients) and food allergy (10 patients). Sensitization to wheat and strawberry was assessed using prick testing, followed by oral challenge test to prove allergy. RESULTS: Wheat sensitization was observed in 9.4% of the studied children with confirmed allergy in 0.4%. Strawberry sensitization was observed in 7.8% of patients, with 2% confirmed allergy. Either sensitization did not influence response of allergy to treatment. Wheat and strawberry sensitizations were positively correlated. CONCLUSION: Wheat and strawberry allergies are not common among Egyptian children with allergic disorders; and did not impact the response to allergy treatment.

ABSTRACT

BACKGROUND: Several studies demonstrated the adverse effect of milk processing on the allergy-protective capacity of raw cow's milk. Whether milk processing also affects the allergenicity of raw milk is hardly investigated. OBJECTIVE: To assess the allergenicity of raw (unprocessed) and processed cow's milk in a murine model for food allergy as well as in cow's milk allergic children. METHODS: C3H/HeOuJ mice were either sensitized to whole milk (raw cow's milk, heated raw cow's milk or shop milk [store-bought milk]) and challenged with cow's milk protein or they were sensitized and challenged to whey proteins (native or heated). Acute allergic symptoms, mast cell degranulation, allergen-specific IgE levels and cytokine concentrations were determined upon challenge. Cow's milk allergic children were tested in an oral provocation pilot with organic raw and conventional shop milk. RESULTS: Mice sensitized to raw milk showed fewer acute allergic symptoms upon intradermal challenge than mice sensitized to processed milk. The acute allergic skin response was low (103 ± 8.5 µm vs 195 ± 17.7 µm for heated raw milk, P < 0.0001 and vs 149 ± 13.6 µm for shop milk, P = 0.0316), and there were no anaphylactic shock symptoms and no anaphylactic shock-induced drop in body temperature. Moreover, allergen-specific IgE levels and Th2 cytokines were significantly lower in raw milk sensitized mice. Interestingly, the reduced sensitizing capacity was preserved in the isolated native whey protein fraction of raw milk. Besides, native whey protein challenge diminished allergic symptoms in mice sensitized to heated whey proteins. In an oral provocation pilot, cow's milk allergic children tolerated raw milk up to 50 mL, whereas they only tolerated 8.6 ± 5.3 mL shop milk (P = 0.0078). CONCLUSION AND CLINICAL RELEVANCE: This study demonstrates that raw (unprocessed) cow's milk and native whey proteins have a lower allergenicity than their processed counterparts. The preclinical evidence in combination with the human proof-of-concept provocation pilot provides evidence that milk processing negatively influences the allergenicity of milk.

ABSTRACT

INTRODUCTION: Poorly developed teachers' competences for managing children's allergies can pose a significant problem for the wellbeing of children in the preschool and school environment. The purpose of this study is to explore the attitudes and theoretical understanding of the management of allergic reactions in children among future teachers. METHODS: A total of 572 future teachers participated in the study, 56% of whom were in the 1st year of undergraduate educational programmes, while 44% were in the 4th year. The participants answered the Teachers' Health Competences Development - Allergy Questionnaire. RESULTS: The future teachers showed positive attitudes towards learning more about different child health issues. There was an average understanding of managing allergic reactions in children (59.4%; SD=16.1% success), with no statistically significant difference regarding the duration of education, science background or the students' self-allergy. There was, however, a statistically significant difference in achievement scores between future teachers in different educational programmes (F(3,568)=6.4, p≤.000). A subgroup of future teachers exposed to basic allergy education in the 1st year and tested again in the 4th year showed significantly better knowledge (Mann-WhitneyU=83.0; p=.008). CONCLUSION: The duration of future education, science background and self-allergy did not influence the level of knowledge regarding the management of allergic reactions in children. A basic educational programme in allergy management had a positive effect on future teachers' knowledge of managing allergic reactions in children. Our study indicates that all future teachers should be included in specific educational programmes in order to develop adequate health competences.

ABSTRACT

PURPOSE: To evaluate the frequency of banana sensitization and allergy among a group of atopic Egyptian children in relation to parental/self reports. METHODS: This is a case-control study included 2 groups of allergic children with and without history of banana allergy, each included 40 patients. They were subjected to skin prick test (SPT) using commercial banana allergen extract and prick-prick test (PPT) using raw banana, in addition to measuring the serum banana-specific IgE. Oral banana challenge was performed in suspected cases. RESULTS: Banana allergy was diagnosed in 3 (7.5%) patients based on positive history of allergy on exposure to banana, positive SPT/PPT and elevated banana-specific IgE. The 3 patients had bronchial asthma with exacerbation upon banana exposure. The PPT results conform with those of SPT both in diagnosis of banana allergy and in the skin reactivity to banana. Serum banana-specific IgE was detectable in the whole studied sample with higher serum level among those without history of banana allergy (P=0.005). Oral banana challenge was negative for 20 patients with history of banana allergy and positive serum banana-specific IgE but negative SPT and PPT. CONCLUSIONS: Self/parental reports of banana allergy is high while the actual banana allergy is uncommon. The PPT seems as reliable as SPT in diagnosis of banana allergy unlike specific IgE which reflects sensitization rather than allergy. Oral food challenge remains the most helpful tool for diagnosis of food allergy in suspected cases.

ABSTRACT

PURPOSE: Recently, allergic disorders in children have increased. The cause of allergic disorders made not clear. Therefore study in aspect of food and nutrition was required to prevent allergic disorders in children, show guide of dietary management. METHODS: This study was done in 78 children with allergy from July, 1997 to September, 1997, investigated family history of allergy and general environment with questionnaire, besides growth levels of children with allergic symptoms, nutrient intakes, eating behavior, and allergy-inducing foods. RESULTS: The results of this study are summarized as follows. 1) Allergic symptoms with a age 2-3 years old were asthma (46%), dermatitis (39%), hypersensitivity skin (7%), urticaria (5%) and rhinitis (5%). At age 4-6 years, asthma was 54%, dermatitis 44%, rhinitis 28%, hypersensitivity skin 10%, and urticaria 3%. Most of the dermatits was caused by unknown etiology, temperature change and house dust mite. Asthma was caused by house dust mite and temperature change. Urticaria was caused by foods and rhinitis was caused by house dust mite. 2) Tomato was the most common food as a cause of allergic disease and peach, mackerel, yoghurt, cheese, and egg were included. Urticaria was provoked mainly by tomato and peach, diarrhea was induced by milk, yoghurt and cheese, vomiting by quail eggs, and swelling lip was induced by tomato. 3) The average daily calory intake was 80% of the RDA at the age of 2-3 years old, 66% at the age of 4-6 year old. Protein and fat intake were similar as RDA. The other nutrients intake at the age of 2-3 and 4-6 years old were 106% and 71% for calcuim, 49% and 52% for iron, 30% and 31% for zinc, respectively. The amount of vitamin intake also lower than RDA for both age groups. CONCLUSION: The average calory intake and other nutrients intake for the children with allergic symptoms were lower than RDA. But they showed relatively normal growth pattern compared with the Korean growth standard. It is necessary to findout the food that provoke the allergic symptoms and make guideline for diet therapy for the children with a various allergic symptoms.
